Description
The Tohatsu MFS140A is a 140HP four-stroke outboard motor built for Australian boat owners who need dependable power on the water. Fitted with a 4-cylinder, in-line, SOHC-4V, water-cooled powerhead displacing 1995cc and running a electronic fuel injection (efi), variable valve lift fuel system, this long (20″) shaft outboard is set up with electric start and remote mechanical control, giving you a straightforward, reliable setup whether you’re heading out for a weekend fish or a longer day on the water.
At 178kg, the MFS140A is engineered to be light enough to handle on the transom while still delivering the torque and acceleration boaters expect from Tohatsu’s four-stroke range. It suits centre console and side console boats from 5.5m to 6.5m wanting light high-horsepower performance, and is finished in Tohatsu Grey to match Tohatsu’s current outboard line-up.
Key features:
– Performs similarly to heavier 150HP outboards that weigh up to 45kg more, thanks to Simpliq Technology
– Industry-first 4-2-1 Performance Tuned Exhaust manifold maximises low-end torque and acceleration
– Automatic timing belt tensioner and roller rocker arms reduce noise, vibration and long-term wear
– Counter-rotation model available for smoother handling in twin-engine installations
– Backed by Tohatsu’s 5-year factory warranty, among the strongest in the outboard market
